The post was home to several units of the U.S. Army Materiel Command, Communications Electronic Command (CECOM) and offices of the Army Acquisition Executive (AAE) that research and manage Command and Control, Communications, Computing, Intelligence, Surveillance and Reconnaissance (C4ISR) capabilities and related technology, as well as an interservice organization designed to coordinate C4ISR, an academic preparatory school, an explosive ordnance disposal (EOD) unit, a 902d Military Intelligence Group Office, a garrison services unit, an Army health clinic, and a Veterans Administration health clinic. Other agencies, including the Federal Bureau of Investigation, and Federal Emergency Management Agency, have presences on the post.
The post was selected for closure by the Base Realignment and Closure Commission in 2005. Most Army functions and personnel were required to be moved to Army facilities in Maryland, Aberdeen Proving Ground, and a few to Ohio by 2011. The fort officially closed on September 15, 2011.
